Outcomes of Laparoscopic Pyloromyotomy with Microscope and Stab Incision vs. Open Pyloromyotomy in Infantile Hypertrophic Pyloric Stenosis; Single Institution Experience

PURPOSE: We attempted to evaluate the outcomes of a newly inaugurated surgical technique of laparoscopic pyloromyotomy with microscope and stab incision (MS-LP) with right upper quadrant transverse open pyloromyotomy (RT-OP), which were performed in a single institution. METHODS: The outcome variables in terms of total anesthesia time, operative time, postoperative emesis, time to full-enteral feeding, postoperative hospital stay, cosmetic result score, medical cost, and postoperative wound complications were compared between the MS-LP and RT-OP groups. RESULTS: Fifty-one consecutive pyloromyotomy cases were enrolled; MS-LP (n=33) and RT-OP (n=18). There was no difference in age, pyloric thickness, and preoperative electrolyte levels between the two groups. The total anesthesia time and operative time of MS-LP were not significantly longer than that of RT-OP. Time to full-enteral feeding and postoperative hospital stay were shorter in MS-LP (20.0±18.3 vs. 35.3±14.8 hrs. and 2.4±1.3 vs. 3.4±1.2 days; p=0.047 and 0.050, respectively). The cosmetic result score and medical cost were significantly higher in MS-LP (9.1±1.0 vs. 7.3±1.2 in terms of scores and 3,501,950±1,093,147 vs. 2,522,474±68,605 in terms of KRW; p=0.001 and 0.021, respectively). No difference in postoperative wound complications was observed between the two groups. CONCLUSION: Laparoscopic pyloromyotomy with microscope and stab incision may suggest recovery benefits with a shorter time to full-enteral feeding and postoperative hospital stay, as well as better cosmetic results than RT-OP. However, MS-LP may induce higher costs.

Appropriate Timing of Bariatric Surgery in Obese Type 2 Diabetes Patients

To combat the associated pandemics of obesity and type 2 diabetes mellitus, clinicians need every tool they can get. Currently, bariatric/metabolic surgery is widely accepted as the most effective treatment for weight loss and glycemic control. Nonetheless, the impact noted in clinical studies seems to have predominantly been on the numerical reductions of bodyweight and blood glucose level after surgery. Past and recent evidence about the role of bariatric surgery in the different stages of the clinical course of type 2 diabetes were presented in this paper. Given the evidence on the efficacy of bariatric surgery for obese patients with type 2 diabetes ranging from pre-diabetes through a long-standing diabetic state with established or end-stage macro- and micro-vascular complications, the overall conclusions are that end organ damage is expected to either stabilize or improve postoperatively in most cases. However, some of these clinical outcomes have not been assessed with a robust method, and many cases are not supported by randomized clinical trials. Available evidence strongly advocates in favor of bariatric surgery in the early phase of this course, possibly in the pre-diabetic or very early diabetic stages. To reserve surgery to more advanced and complicated stages of the disease seems to confer fewer benefits in the clinical course of diabetes and might expose these more frail patients to the possible side effects of a rapid weight loss.

Surgical Outcomes of Single-port Laparoscopic Appendectomy versus Conventional Laparoscopic Appendectomy in Children: Preliminary Report of a Prospective Randomized Trial / 소아외과

PURPOSE: Currently the substantial clinical benefits of single-port laparoscopic appendectomy (SLA) over conventional three-port laparoscopic appendectomy (CLA) are equivocal. The aim of this study was to compare surgical outcomes between SLA and CLA in children with acute appendicitis. METHODS: A single blind prospective randomized single center study was performed to compare the surgical outcomes of SLA and CLA. A total of 105 patients were randomized and various parameters were analyzed, 52 patients with SLA and 53 patients with CLA between July 2013 and March 2014. Patients with sonographically confirmed acute appendicitis were randomly assigned to receive either SLA or CLA. The outcome measurements were operating time, wound complication, and intraperitoneal morbidities, postoperative pain score and cosmetic result score. RESULTS: Operating time is significantly longer in SLA (70.4+/-26.7 minutes vs. 58.0+/-23.4 minutes; p=0.016). There were no significant differences in the postoperative wound complication rate and intraperitoneal morbidities between two groups. There were no significant differences in postoperative resting pain score (6.6+/-2.5 vs. 6.3+/-2.5; p=0.317) and activity pain score (6.9+/-2.4 vs. 6.3+/-2.5; p=0.189), and the cosmetic result score (9.2+/-1.1 vs. 9.1+/-1.4; p=0.853). CONCLUSION: Although SLA would be a safe and feasible procedure in children, SLA could not demonstrate the clear benefit over CLA.
